摘要： In order to monitor a state of a battery, a threshold value of an internal impedance of the battery is first determined. It is prepared an approximate expression indicating a correlation between a residual capacity of the battery and an internal impedance of the battery which is greater than the threshold value. The internal impedance of the battery is then measured. When the measured internal impedance is the threshold value or less, the residual capacity is determined as an initial value. When the measured internal impedance is greater than the threshold value, the residual capacity is monitored with the approximate expression.

摘要： The swing centers of guide shafts in inclination adjustment of an optical head are set to be on a plane which is perpendicular to a predetermined radial direction of an optical disk and has thereon the rotation axis of a disk motor. When the inclination adjustment of the optical head is conducted, relative gap variation between the optical head and the optical disk does not occur, and the inclination adjustment is realized within a movable range of an objective lens. The inclination angle of the optical head in a radial direction of the optical disk is adjusted by simultaneously moving upward or downward ends of two guide shafts, and the inclination angle of the optical head in a tangential direction of the optical disk can be adjusted by moving upward and downward one end of at least one of the guide shafts.

摘要： The improvement proposed relates to the dipole ring magnet in a magnetic field generator for magnetron plasma in an apparatus for plasma sputtering or plasma etching. Different from the conventional dipole ring magnet, which is an assembly of anisotropic columnar segment magnets in a circular arrangement each in an integral columnar form, each of the segment magnets according to the first aspect of the invention is divided into upper and lower halves and the gap space held between the upper and lower halves is varied from position to position so that the uniformity of the magnetic field formed inside of the dipole ring magnet is increased in the horizontal direction with consequently increased uniformity of the plasma density generated thereby. Instead of dividing each of the segment magnets into the upper and lower halves, according to the second aspect of the invention, the circular arrangement of the segment magnets is not regular and symmetrical but assymmetrical relative to the direction of the magnetic field so that similar improvements to those in the first aspect of the invention can be accomplished in the uniformity of the magnetic field and in the density of the plasma.
摘要翻译：提出的改进涉及用于等离子体溅射或等离子体蚀刻的装置中用于磁控管等离子体的磁场发生器中的偶极环磁体。与传统的偶极环磁体不同，传统的偶极环磁体是圆柱形排列的各向异性圆柱形磁体的组件，每一个都是一体的柱形，根据本发明第一方面的每个分段磁体分为上半部分和下半部分，保持在上半部和下半部之间的间隙空间在位置之间变化，使得在偶极环磁体内形成的磁场的均匀性在水平方向上增加，从而增加了由此产生的等离子体密度的均匀性。根据本发明的第二方面，代替将每个分段磁体分成上半部分和下半部分，分段磁体的圆形布置不是相对于磁场方向的规则和对称但不对称的，因此类似的改进可以在磁场的均匀性和等离子体的密度中实现本发明的第一方面。

摘要： The invention relates to an apparatus for producing a magnetic field in a space between two oppositely arranged permanent magnet discs, which is suitable for use in magnetic resonance imaging (MRI). An object of the invention is to reduce the size and weight of the yoke connecting the two permanent magnet discs without causing magnetic saturation of the yoke in view of the fact that magnetic saturation of the yoke leads to the appearance of leakage flux and consequential lowering of the uniformity of the magnetic field. The object is accomplished by regulating the cross-sectional area of the whole magnetic path in the yoke, A.sub.y, such that the following equation holds: A.sub.y =1/a.times.A.sub.m B.sub.m /B.sub.ys, where A.sub.m is the cross-sectional area of magnetic path in each permanent magnet disc, B.sub.m is the magnetic flux density in each permanent magnet disc at normal temperature, B.sub.ys is the saturation magnetic flux density of the yoke at normal temperature, and a is a coefficient the value of which is not larger than 1 and not smaller than 0.6.

摘要： The invention relates to a cylindrical magnet apparatus for producing a uniform magnetic field in a predetermined direction within the cylindrical hole in the apparatus. The apparatus is suitable for use in NMR imaging. Essentially the apparatus is an assembly of a plurality of dipole ring magnets in a coaxially juxtaposed arrangement. Each ring magnet is constructed of a plurality of cross-sectionally trapezoidal segments which are arranged annularly, and each segment is an anisotropic magnet block magnetized in a suitable direction. To acquire a good balance between the material cost and the gross weight of the apparatus a selected portion of the assembly of dipole ring magnets is made of a rare earth alloy magnet, whereas the remaining portion is made of a ferrite magnet. In one embodiment of the invention, in each segment of each ring magnet an end part on the radially inner side of the ring magnet is made of a rare earth alloy magnet whereas the remaining part is made of a ferrite magnet.
